Earlier today we reported that the iPhone 5 would have dual-mode chipset supporting both the GSM and CDMA networks with a single model. And now The Wall Street Journal is reporting that iPhone 5 will be launched simultaneously on AT&T, Verizon and Sprint. WSJ posted:

Sprint Nextel Corp. will begin selling the iPhone 5 in mid-October, people familiar with the matter said, closing a huge hole in the No. 3 U.S. carrier's lineup and giving Apple Inc. another channel for selling its popular phone.

Top U.S. carrier Verizon Wireless and No. 2 AT&T Inc. will begin selling the phone in mid-October as well, two of the people said. Sprint had more than 52 million subscribers at the end of the second quarter, compared with 106 million for Verizon and nearly 99 million for AT&T.

Sprint will also carry the iPhone 4, starting at the same time, one person familiar with the situation said.

As we wrote earlier, it looks like iPhone 5 launch date is zeroing in on October with an announcement coming in September.
